Embodiment Construction

[0040] The invention relates to a shedding module (1) for selectively moving a shedding element using a non-selectively movable lifting element, preferably in the form of a knife. At least two sets of lifting elements are provided, which are movable up and down in antiphase in the range of motion according to an adjustable range of motion.

[0041] The motion zone (Z) is in figure 2 is shown as a shaded area in and can be considered as the (possibly smallest) enclosing rectangle of the projection on the lifting element level.

[0042]In order to move the lifting elements up and down in antiphase, the shedding module (1) is provided with a drive system. The drive system includes the following components:

[0043] - transmission means for transmitting motion from a first driven, preferably rotating shaft (2) to a second shaft (3) according to a constant transmission ratio, the axis (A) of the first driven shaft (2) at extending upward in one direction, the axis (B) of the se...

Abstract

The invention relates to a shed-forming module (1) for the selective movement of shed-forming elements. The module includes at least two sets of lifting elements which are movable up and down in antiphase in a movement zone, and a drive system, comprising: transfer means for transferring the movement according to a constant transfer ratio from a first driven shaft (2), the axis (A) of which extends in a first direction, to a second shaft (3), the axis (B) of which extends in a second direction; conversion means for converting the movement of the second shaft (3) into an oscillating movement around a third axis (C) which extends at a distance from and in the same direction as the second direction, with the conversion means comprising at least one follower component (4) which is movable in oscillation around the third axis (C); and connecting means which create the connection between said follower component (4) and the lifting elements in the movement zone, wherein the conversion means are provided in a closable housing (30), the housing comprises at least one opening which forms a passage for the connecting means, and the connecting means extend fluid-tightly through the opening.

Description

technical field [0001] The invention relates to a shedding module for selectively moving shedding elements using lifting elements, comprising at least two sets of lifting elements movable up and down in opposite phases and a drive system provided with first and second drive means , the first and second driving means are swingably movable to drive the lifting element. [0002] The invention also relates to a Jacquard machine provided with such a shedding module, a loom provided with such a shedding module, in particular a loom provided with such a Jacquard machine. Background technique [0003] When a fabric is woven on a loom, the horizontal positioning of the warp yarns during successive weaving cycles relative to the weft yarns introduced in each cycle. In this case, the positions of the warp threads in the successive weaving cycles are determined such that the weaving process produces a fabric with a predetermined weaving pattern. This positioning of the warp threads re...
